I`ve used full reverse twice on the Ejet, both times on the 170 max landing weight into LCY wet runway icing speeds in gusty wind. Its been that it all feels a bit fast and a bit short feeling with a Vap of 140kts + . Both times stopping has been very good and could maybe of got away without the reverse.
It is very noisy in the cabin, a lot more so than the Airbus or 737 using reverse.
The 190 has never been an issue, with the bigger wing it lands a lot slower.
